- Before attempting to fix the faucet, it’s important to understand the type of faucet you have and identify the source of the leak.
- With the right tools and materials, fixing a leaking bathtub faucet is usually a straightforward process that you can do yourself.
Understanding the Problem
A bathtub faucet leaking when the shower is on can be a frustrating problem. It can cause a decrease in water pressure, wasting water, and increasing your water bill. Understanding the problem is the first step in solving it.
The most common cause of a bathtub faucet leaking when the shower is on is a failed shower diverter valve. The diverter valve is responsible for directing water flow from the bathtub faucet to the showerhead. When the valve fails, water can leak out of the faucet while the shower is on.
Another cause of a leaky bathtub faucet is hard water buildup. Over time, minerals in the water can build up inside the faucet and cause it to leak. This can be prevented by regularly cleaning the faucet with a solution of vinegar and water.
Sometimes, the problem can be as simple as a partially engaged diverter. If the diverter is not fully engaged, water can leak out of the faucet while the shower is on. To fix this, simply push the diverter all the way in.
If you are experiencing a bathtub faucet leaking when the shower is on, it is important to address the problem as soon as possible. Ignoring the problem can lead to further damage to your plumbing system and increased water bills.
Distinguishing the Type of Faucet
Before attempting to fix a leaky bathtub faucet, it’s important to determine the type of faucet you have. There are two main types of bathtub faucets: two-handle faucets and single-handle bathtub faucets.
Two-Handle Faucet
A two-handle faucet has separate handles for hot and cold water. The handles are typically located on either side of the spout. To turn the water on, you need to turn both handles. Two-handle faucets can be further divided into compression faucets and washerless faucets.
Compression faucets have a stem that moves up and down to control the flow of water. When the stem is raised, water flows through the faucet. When the stem is lowered, the water stops. Compression faucets have washers that can wear out over time, causing leaks.
Washerless faucets use a ball, cartridge, or disc to control the flow of water. These faucets are less prone to leaks than compression faucets, but they can still leak if the parts wear out or become damaged.
Single-Handle Bathtub Faucet
A single-handle bathtub faucet has one handle that controls both the hot and cold water. These faucets are typically located on the wall above the bathtub. Single-handle faucets can be further divided into ball faucets, cartridge faucets, and disc faucets.
Ball faucets have a rotating ball inside the faucet that controls the flow of water. The ball has small openings that align with the hot and cold water inlets to control the water temperature. Ball faucets can leak if the O-rings or springs inside the faucet wear out.
Cartridge faucets use a cartridge to control the flow of water. The cartridge has small openings that align with the hot and cold water inlets to control the water temperature. Cartridge faucets can leak if the O-rings or cartridge become damaged.
Disc faucets have two ceramic discs that control the flow of water. The discs move up and down to control the flow of water and the temperature. Disc faucets can leak if the discs become damaged or the O-rings wear out.
Common Causes of Leaks
No matter what type of faucet you have, leaks can occur due to a variety of reasons. Some common causes of leaks include worn out washers, damaged O-rings, corroded valve seats, and loose parts. If you’re not sure what’s causing your faucet to leak, it’s best to call a professional plumber to diagnose and fix the problem.
Tools and Materials Required
To fix a bathtub faucet that leaks when the shower is on, you will need a few tools and materials. Here is a list of items you will need:
Tools
- Screwdriver
- Socket wrench

Before you start, make sure you turn off the water supply to the bathtub. This will prevent any accidental flooding.
Once you have the necessary tools and materials, you can begin the repair process. It’s important to note that the specific tools and materials required may vary depending on the type of bathtub faucet you have and the extent of the damage.
If you’re not sure which replacement part you need, you can take the old part to a hardware store and ask for assistance. They should be able to help you find the right replacement part for your bathtub faucet.
Overall, with the right tools, materials, and knowledge, fixing a leaking bathtub faucet that drips when the shower is on can be a relatively simple DIY project.
Safety Precautions
When dealing with a leaking bathtub faucet, it is important to take certain safety precautions to avoid any accidents or further damage to your plumbing system. Here are a few things to keep in mind:
Shut off the water: Before attempting any repairs, make sure to shut off the water supply to your bathtub. This will prevent any water from flowing through the pipes and causing further leaks or damage. Locate the water valve or shut-off valve near your bathtub and turn it off.
Protect your hands: When working with plumbing fixtures, it is important to wear protective gloves to avoid any cuts or injuries. This is especially important when dealing with sharp or rusted parts.
Use the right tools: Make sure to use the right tools for the job. Using the wrong tools can damage the plumbing fixtures and make the problem worse. It is also important to use tools that are in good condition and not rusted or worn out.
Follow the instructions: When attempting to repair a leaking bathtub faucet, make sure to follow the instructions carefully. If you are unsure about any steps, consult a professional plumber.
Be careful with chemicals: When using any chemicals to clean or repair your plumbing fixtures, make sure to follow the instructions carefully. Some chemicals can be dangerous if not used properly, and can cause harm to you or your plumbing system.
By following these safety precautions, you can avoid accidents and ensure that your plumbing system is properly maintained. Remember to always consult a professional plumber if you are unsure about any repairs or maintenance tasks.
Identifying the Source of the Leak
If you notice water leaking from your bathtub faucet when the shower is on, it’s important to identify the source of the leak before attempting to fix it. Here are some common areas to check:
Bathtub Spout
The first place to check is the bathtub spout. If water is coming out of the spout instead of the showerhead, it may be due to a faulty diverter. The diverter is a valve that directs water from the spout to the showerhead. If it’s not working properly, water can leak out of the spout even when the shower is on.
Handle
Another common source of leaks is the handle. If water is dripping from the handle, it could be due to a worn out washer or seal. The handle may also be loose, causing water to seep out around the base. Tightening the handle or replacing the washer or seal should fix the problem.
Valve and Stem
The valve and stem are the components that control the flow of water in the faucet. If they are worn or damaged, water can leak out of the faucet. To check the valve and stem, turn off the water supply and remove the handle and trim plate. You should be able to see the valve and stem at this point. If they are corroded or damaged, they will need to be replaced.
Pipes
If none of the above components are the source of the leak, it could be due to a problem with the pipes. Over time, pipes can become corroded or damaged, leading to leaks. If you suspect a problem with the pipes, it’s best to call a plumber to inspect and repair them.
By identifying the source of the leak, you can determine the best course of action to fix it. Whether it’s a faulty diverter, a worn out washer, or a damaged valve, addressing the issue promptly can prevent further damage and save you money on your water bill.
Steps to Fix a Leaking Bathtub Faucet
A leaking bathtub faucet can be a frustrating problem, especially when the water is leaking even when the shower is on. Fortunately, fixing a leaking bathtub faucet is a relatively easy task that can be done by anyone with basic plumbing knowledge. Here are the steps to fix a leaking bathtub faucet:
Turn off the water supply: Before starting any plumbing work, it is important to turn off the water supply to the bathroom. The shut-off valve is usually located in the basem*nt or crawl space of the house. Turn the valve clockwise to stop the water flow.
Remove the faucet handle: Use a screwdriver to remove the screw that holds the faucet handle in place. Once the screw is removed, use a handle puller to remove the handle from the faucet.
Remove the stem assembly: Use a wrench to remove the packing nut that holds the stem assembly in place. Once the packing nut is removed, pull the stem assembly out of the faucet.
Replace the rubber washer: The rubber washer is located at the bottom of the stem assembly. If the washer is worn or damaged, replace it with a new one.
Replace the seat washer: The seat washer is located inside the faucet and is held in place by a screw. If the washer is worn or damaged, replace it with a new one.
Replace the valve stem: If the rubber washer and seat washer are in good condition, the problem may be with the valve stem. Replace the valve stem with a new one.
Reassemble the faucet: Once all the parts have been replaced, reassemble the faucet in the reverse order that you took it apart. Make sure to tighten all the screws and nuts securely.
Test the faucet: Turn on the water supply and test the faucet for leaks. If the faucet is still leaking, you may need to replace the entire faucet assembly.
In conclusion, fixing a leaking bathtub faucet is a simple task that can save you money on your water bill and prevent further damage to your plumbing system. By following these steps, you can easily repair your leaking bathtub faucet and enjoy a watertight seal once again.
Dealing with Stubborn Parts
Sometimes, even after following all the steps to fix a leaking bathtub faucet, some parts may still refuse to budge. This can be due to rust, corrosion, or mineral deposits. Here are some tips for dealing with stubborn parts:
Use vinegar: If the problem is due to mineral deposits, soaking the affected parts in white vinegar can help dissolve the buildup. Simply fill a plastic bag with vinegar and wrap it around the faucet, making sure the affected parts are submerged. Leave it on for a few hours or overnight, then remove the bag and rinse the parts with water.
Apply Teflon tape: If the threads on the hardware are corroded or rusted, applying Teflon tape can help create a better seal. Wrap the tape around the threads in a clockwise direction, making sure to overlap the tape slightly. This can help prevent leaks and make it easier to remove the hardware in the future.
Use wax or sealant: If the problem is due to a corroded or damaged seal, applying wax or sealant can help create a better seal. Simply apply the wax or sealant around the affected area and allow it to dry completely before turning on the water.
Use a bolt extractor: If a bolt or allen screw is stuck, using a bolt extractor can help remove it. Simply drill a hole into the center of the bolt or screw, then insert the extractor and turn it counterclockwise. This can help loosen the bolt or screw and make it easier to remove.
Remember, if you’re still having trouble with stubborn parts, it may be best to call a professional plumber for assistance. They have the tools and expertise necessary to handle even the most stubborn plumbing problems.
Replacing a Shower Diverter
If you have a bathtub faucet that leaks when the shower is on, it might be time to replace the shower diverter. The shower diverter is the valve that controls the flow of water from the bathtub spout to the showerhead. Over time, the diverter can become worn or damaged, which can cause leaks and other problems.
To replace the shower diverter, you will need to follow these steps:
Turn off the water supply to the bathtub. This can usually be done by turning off the water valve located near the bathtub or by shutting off the main water supply to the house.
Remove the old shower diverter. The method for removing the diverter will depend on the type of diverter you have. Some diverters are held in place by a screw, while others are held in place by a clip or other mechanism. Refer to the manufacturer’s instructions or consult with a plumber if you are unsure how to remove the diverter.
Install the new shower diverter. Again, the method for installing the diverter will depend on the type of diverter you have. Follow the manufacturer’s instructions or consult with a plumber if you are unsure how to install the diverter.
Test the new diverter. Turn on the water supply to the bathtub and test the new diverter to make sure it is working properly. If there are any leaks or other problems, you may need to adjust the diverter or consult with a plumber.
Replacing a shower diverter can be a simple and straightforward process, but it is important to take your time and follow the manufacturer’s instructions or consult with a plumber if you are unsure how to proceed. By replacing a worn or damaged shower diverter, you can prevent leaks and other problems and ensure that your bathtub faucet and shower combo are working properly.
Checking the Water Pressure
If your bathtub faucet is leaking when the shower is on, it could be due to low water pressure. Checking the water pressure is an important step in diagnosing the problem.
You can check the water pressure by using a pressure gauge. Attach the gauge to an outdoor faucet or laundry room faucet and turn on the water. The gauge will give you a reading of the water pressure in PSI (pounds per square inch).
The ideal water pressure for a home is between 40 and 60 PSI. If the pressure is too low, it can cause problems with the plumbing system, including leaks. If the pressure is too high, it can damage the plumbing fixtures and appliances.
There are several reasons why the water pressure may be low. It could be due to a clogged faucet aerator, a faulty pressure regulator, or a leak in the plumbing system.
If the water pressure is low, you can try cleaning the faucet aerator to remove any debris that may be blocking the flow of water. If that doesn’t work, you may need to replace the pressure regulator or call a plumber to locate and fix any leaks in the plumbing system.
It’s also important to check the water temperature when checking the water pressure. If the water pressure is low and the water is not hot enough, it could be due to a problem with the water heater. Check the temperature setting on the water heater and make sure it is set to the appropriate temperature.
By checking the water pressure and temperature, you can determine if these factors are contributing to the bathtub faucet leaking when the shower is on.
